Partial-failure cleanup audit for Compozy Go functions. An agent skill from compozy/compozy.

  • A changed function acquires
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Opens more than one fallible resource before returning
  • Pure transformations

What it does

Eng Cleanup Failure Paths is an agent skill from compozy/compozy. Partial-failure cleanup audit for Compozy Go functions. Use when a changed function acquires, registers, starts, claims, leases, or opens more than one fallible resource before returning. Do not use for pure transformations, read-only helpers, or test-only code.

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/cleanup-table.md` and `references/test-failure-paths.md`).

The repository describes itself as: An operating system for AI agents. Plug in the agent CLIs you already use (Claude Code, Codex, Gemini CLI, Cursor) and they become a team: they split the work, hand tasks to each… The licence is MIT.

When your agent uses it

  • A changed function acquires
  • Opens more than one fallible resource before returning
  • Pure transformations
  • Read-only helpers

Example prompts

  • “/eng-cleanup-failure-paths”

What it can do on your machine

Read from SKILL.md and the folder at commit eec2ed1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Eng Cleanup Failure Paths loads about 527 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~527
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cleanup Failure Paths

Prove ownership across the affected function's acquisitions and exits. Account for the whole lifetime when a local edit changes cleanup; a matrix in working notes is useful for complex ownership, not a required report.

  • Identify acquired resources, their owners, cleanup/error policy, shutdown order, and any explicit ownership transfer. Use the matching rows of references/cleanup-table.md; read the complete table when the ownership chain spans its rules.
  • Walk success, error, cancellation, and reachable recovery exits after each acquisition. Release or transfer every live resource. Preserve the primary error and handle secondary cleanup failures.
  • Keep responses and writers request-bound. Detached execution needs a bounded lifetime and cancel/stop surface; subprocess trees retain process-group parity and cancel-then-grace shutdown.
  • Repair affected exits together. Split ownership when it cannot be proved locally, not because a function crosses an arbitrary defer-count threshold. Leave unrelated cleanup debt outside the change.

Before changing coverage, name the invariant, owning layer, and existing suite. Use eng-consolidate-test-suites only if placement is unclear and eng-test-conventions for Go test shape. references/test-failure-paths.md supplies patterns for the distinct failure class being changed. Reuse coverage that already proves the invariant; multiple syntactic returns do not imply multiple tests.

Inject failures through an interface or real I/O boundary and assert actual release, reuse, closure, or termination. A mock-call count alone does not prove cleanup. Complete when affected ownership paths are sound and their owning checks pass; the enclosing workstream owns delivery gates.
